I agree with those objectives. I am not sure why you used to consider them as "liberal" as this goal is not limited to one party or group. The difference is how that goal is achieved.
What I oppose is seeking to achieve those objectives via any means. We are called to "be Christ" to the world (not just to tell people of the love of God but to love people with the love of God). But we are called to do this "kingdom work" through kingdom means.
The Democrat Party is Progressive Humanism, which focuses on helping the poor, fighting inequality, discrimination, hate,and unnecessary wars (admirable goals). The slogan is "good without a god". I am not saying that they are not trying to do good (they are). Perhaps this is why they are such a dangerous evil. They strive to do "good without a god". We are responsible for what we support, not only in politics but in everything.
I am not a Republican for similar reasons. While their platform is not directly immoral, I believe that the goal (those "liberal objectives", as you put it) cannot be reached through political means. My ties are to Christ. As a Christian I cannot support immorality. I cannot be "for Christ" and "against Christ" at the same time. I do not believe we, as Christians, need to strive to do "good without a god".
